A fixture is disclosed which can reliably attach an attachment member, such as a cylinder, to an attachment site, such as a frame. The fixture includes a fixing portion, which faces the attachment site at the side of the attachment site and is fixed to the attachment site, and a contact portion, which is disposed at the side opposite from the attachment site, with the attachment member therebetween. The contact portion is integrally coupled to the fixing portion, point-contacts or line-contacts the attachment member, and is configured to push the attachment member to the attachment site in a state where the fixing portion is fixed to the attachment site. A webbing take-up device including this fixture is also disclosed.

What is claimed is: 1. A fixture for fixing a columnar or cylindrical attachment member to a predetermined attachment site, at the side of the attachment site, the fixture comprising: a pair of fixing portions that are fixed to the attachment site and face the attachment site at both sides of the attachment member along a direction intersecting a longitudinal direction of the attachment member; and a contact portion that is disposed at the side opposite to the attachment site, with the attachment member therebetween, is integrally coupled to the pair of fixing portions, point-contacts the attachment member, or line-contacts the attachment member along the longitudinal direction of the attachment member, and pushes the attachment member to the attachment site in a state where the fixing portions are fixed to the attachment site, further including a fixture body that is formed in a concave shape opening toward the attachment site, and in which the fixing portions are formed at both ends of the open side, and on whose inner peripheral portion the contact portion is formed, wherein the dimension from the surface of the fixture body facing the attachment site to where the contact portion contacts the attachment member, along the direction of opening of the fixture body, is set to be less than an outer dimension of the attachment member along the direction of opening, and wherein the contact portion is formed so as to protrude toward the open side from a substantially center portion of the inner peripheral portion of the concave shape portion of the fixture body. 2. A webbing take-up device including the fixture of claim 1. 3. The fixture of claim 1, wherein the attachment member comprises a circular columnar or circular cylindrical member formed by processing a pre-formed member. 4. The webbing take-up device of claim 2, wherein the attachment member comprises a circular columnar or circular cylindrical member formed by processing a pre-formed member. 5. A webbing take-up device comprising: a frame that directly or indirectly rotatably axially supports a spool to which a base end of a long band-like webbing belt is attached; a pretensioner that accommodates a piston inside a cylinder that is formed in cylindrical shape where one end is open and is disposed at the side of the frame, with the pretensioner pushing the piston toward one end of the cylinder to cause the spool to rotate in a direction in which the spool takes up the webbing belt; and a fixture comprising a fixture body fixed to the frame and a contact portion that point-contacts, or line-contacts along the axial direction of the cylinder, the outer peripheral portion of the cylinder, and retains the frame with the contact portion pushing the cylinder against the frame in a state where the fixture body is fixed to the frame, wherein the fixture body is formed in a concave shape that opens toward the cylinder, and in which fixing portions are formed at both ends thereof, and on whose inner peripheral portion the contact portion is formed, wherein the dimension from the contact portion of the inner surface of the fixture body facing the cylinder to where the fixing portions contact the frame is set to be less than an outer dimension of the cylinder such that the fixture body resiliently retains the cylinder against the frame, and wherein the contact portion is formed so as to protrude toward the open side from a substantially center portion of the inner peripheral portion of the concave shape portion of the fixture body. 6. The webbing take-up device of claim 5, wherein the cylinder comprises a cylinder formed by processing a pre-formed pipe-shaped member.
